ST121A Abbe refractometer

The ST121A Abbe refractometer is an instrument capable of measuring the refractive index ND and average dispersion NF-NC of transparent, semi transparent liquids or solids. If a thermostat is connected to the instrument, the refractive index ND can be measured within the temperature range of 0 ℃~70 ℃, and the percentage of sugar concentration in the sugar solution can be measured from 0-95% (equivalent to a refractive index of 1.333-1.531). Therefore, this type of instrument is an indispensable equipment for factories, schools, and powder grinding units in the petroleum industry, oil and fat industry, pharmaceutical industry, paint industry, food industry, daily chemical industry, sugar industry, and geological exploration.
